Frequently Asked Questions

What will the ERB testing policy be for incoming Pre-K and Kindergarteners?

After much consideration, we at Columbia Grammar & Prep have decided to follow ISAAGNY’s recommendation and no longer require the ERB results as part of our application process. Moreover, we will no longer accept or consider the results of the ECAA if a child has taken the assessment. The rest of our application process will remain the same.

What is your deadline for receiving applications?

Applications are available the day after Labor Day and are accepted until our deadline of December 1st.

Is there a Parent Interview required as part of the Admissions Process?

While we are happy to answer any questions that parents may have, Columbia Grammar & Preparatory School does not interview the parents of prospective students as part of the Admissions process.

How many students are enrolled in CGPS?

We have approximately 1300 students from Pre-K up through 12th Grade. As a co-educational school we have an equal number of males and females enrolled.

What is your affiliation with Columbia University?

Columbia Grammar School was founded in 1764, just 10 years after the founding of Kings College, which became Columbia College, now part of Columbia University. Originally established as a boys preparatory school for Kings College, Columbia Grammar School functioned for 100 years under the direct auspices of the college.

In 1864, the trustees of Columbia College terminated their relationship with Columbia Grammar School, and the school became a proprietary institution, only achieving its non-profit status in 1941.

What is the Student/Teacher ratio?

The current Student/Teacher ratio is 5.7 to 1.

Do you offer a nursery school program?

We offer classes beginning at the Pre-Kindergarten level. A Pre-Kindergarten student must be Four years old by August 1st of his/her Pre-Kindergarten year.
